STEAM -RAD!ATO.R.

SPECIFICATION forming part. of Letters Patent No, 867,083, dated July 26, 1887.

Application filed December 18, 1886. Serial No. 221,992. (No model.)

To all whom it may concern:

Be it known that 1, Josnrn ASKINS, a citizen of the United States, anda resident ofLima, in the county of Allen and State of Ohio, have invented a new and useful Improvement in Steam-Radiators, of which the follouing is a specification.

My invention is radiators.

Figure l is a perspective of aseries of loops or radiators united. tional View of one of the radiators.

My radiator is composed of a number of sections or loops, cast separately and united near the bottom by nipples, and bolted together near the top.

The construction and operation of my radiator-loop are as follows:

The main part A is castin one piece having a hollow interior forming the chambers B G M and passage Q. Near the bottom of chamber M is a port for the admission of steam. There is also a corresponding port on the opposite side, so that when a number of loops are combined they can be connected by ordinary pipean improvement in steam- I nipples. Through the top and bottom of chambers B O are holes,into which the open-ended wrought-iron tubes E D are inserted and Se cured. Thelowerendsofthetubesarescrcwed securely into the holes in the base, while the upper ends are secured by nut H, having an' form a radiator of any desired size or capacity,

by placingthem face'to face and bolting them together through the holes in lug K, the bottoms being first secured together by connecting pipes or nipples screwed into the holes or ports in the chamber M. On the faces at the top will be seen notches R and lugs S. After two of the loops or radiators have been se- Fig. 2, is a vertical sec N N, chambers B O, and through passage Q.

The contact of the hot steam on all sides of the pipes D E heats the airin the pipes, when it rises and escapes at the top, causing a con- .tinuous circulation of air through the tubes,

the cold air being taken from the floor, heated, and passed off into the room. again from the tops of the pipes. I

The throat N is only about half the-size of throat N, and while steam has equally free entrance to both, the greater quantity passes through the throat N, establishing a circulation in the chambers, filling the chamber B first and flowing into chamber 0 through the passage Q.

\Vhat I claim is- 1. In asteam-radiator,the combination,with the singlepieee casting A, forming the steamchambers, of the Wrought-iron open-ended tubes secured rigidly in the bottom of the casting, but passing through the casting at the top and secured by the countersunk nut H at that allows for the unequal expansion of the wrought and cast iron parts, as and for the purpose set forth.
